iiPEGIFIGATIQN forming part of Letters Patent No. 746,817, dated December 15, 1903.

application filed August 14. 1903. fierial No. 169,526- (Ndmodeld To DQZZ whom, it ntaycmwcr'n: Be it known that I, WILLIAM D. GOLD, a citizen of the United States, residing at Car thage, in the county of Smith and State ofTennessee, have invented certain new and useful Improvementsin-Stoves; and I do declare the following to be av full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appere tains to make and use the same, reference beinghad to the accompanyingdrawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to newand useful improvementsinsioves; anditconsistsinthe provision of means whereby different kinds of fuel may hesuccessfnlly burned by the provision of the peculiar arrangement of grates and in the provision of meanswhereby the smoke maybe consumed and affording means whereby rooms in which the stove is positioned may be thoroughly ventilated.

The invention consists, further, in various. details of construction and in combinations and arrangements of parts, which 'will be hereinafter fully described and then specifically defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings Figure 1 is'a sectional perspective view of my improved stove. Fig. 2 is a rear elevation of the stove complete, showing the vent or air-inlet .flues. Fig. 3 is a detail view of the under or'stationary grate. Fig. 4: is a detail view of acylindrical ventilator-adapted to restupon the grate when burning a certain kind of fine fuel. Fig. 5 is adetailview of a similar cylinder which is adapted to rest upon the cylinder shown in Fig. 4 to form a pyramidal ventilator for burning slack, and Figs. 6 to 16, inclusive,-are detail views.

Reference now being had to the details of the drawings by letter, Adesignates thebase portion of thestove, supported by legs A, and B designates an ash-box, underneath'said base portion provided with a suitable door, and mounted upon the platform of the base A, which is provided with an annular rib or its lower end fitting to the flange a and has a cut-away portion C The upper edge of the cylindrical portion of the shell 0 has scallops or. recesses C at intervals, and resting upon the upper end of said shell is a ring D, which is of a largergdiameter, than the body portion ofthe shell 0 and has series of apertures D in the portion. which overhangs the shell 0. Said ring D has an annular flange d, and resting upon the portion of said ring inside "of the flange d is agrate E, a detail view of which is shown in one of the figures of the drawings, said grate having a series of radial openings E and at the center intersecting crossbars P, which span a circular-outlined of said bars is an aperture f, while shoulders 'are provided near the ends of said bars. Surrounding a flange G about the circularontlined aperture F is a movable grate H, having series of radial apertures H therein which are adapted as the movable grate is rotated to close or partially close the apertures in the grate E, or, if desired, the apertures in the two grates may be brought into registration with one another. Said movable grate isprovidedwith an arm it, having a crank h, which passes underneath the circular ringD and projects through the opening intermediate the ends of the shell 0 in a convenient position to receive a shaking-handle H Resting upon the-ring D is a tire-pot made up, preferably, of four sections and designated in the drawings by letter K. Said firepot has a series ,of integral flanges K, K and K thereon, the former of which, K, is positioned a short distance above the flange of the ring D, forming with the surrounding wall of the stove a hot-air compartment. The second flange K is provided with a series of circumferential cut-away portions 10, while the circumference of the lire-pot intermediate the flanges K and K has apertures 1 formed therein, through which the heated air passing through the recesses about the o enin E and at the point of intersection circumference of the flanges it may pass a through into the interior of the stove for the purpose of providing heated air to assistfin furthering the combustion of gases within the fire-pot. The third flange about the fire flange a, is a shell 0, having a flange C atpot supports the cone N, made up of two sections which are securely fastened together,

the upper portion of the cone being of cylindrical shape, as at N, to receive a pipe for conveying smoke from the fire-pot. Upon the inner circumference of the fire-pot adjacent to its lower end is a flange O, which is adapted to support fire-brick P, which have apertures P therein adapted to register with the apertures 1, formed in the circumference of the fire-pot.

Resting upon the flange K is a band Q, having a series of scallops or outwardly-flaring portions Q designed to be positioned adjacent to each of the apertures in the wall of the fire-pot and provided for the purpose of allowing air to readily enter said apertures, but to prevent soot or ashes from coming out of the firepot. Said corrugations or outwardlyflaring portions are so constructed that should any ashes happen to come out of the holes they will be directed back by gravity through the holes whence they came. The outer wall of the stove is designated in the drawings by letter R, and fastened to the latter a little above the shoulders 'n of said cone is a circular disk J, with its bottom largely cut away and is provided with a flange J and is adapted to cooperate with the outer shell R to hold the air in contact with said cone. Resting upon the upper end of the i connect said top with a central ring L which the cylindrical end N of the cone.

is of a size adapted to let the smoke-pipe pass through it after the latter is made to fit over A conveyance-drum S is adapted to fit over a flange L of said top, and apertures open near the top of the drum for connection to pipes through which heat may be conveyed to registers located in various rooms, while the smoke-pipe fits over the end of the cylindrical part of the cone and extends centrally through the heating-drum.

When it is desired to adapt the stove to use various kinds of fuels, the plates T and T may be placed over the central opening in the grate, or if desired to build up a pyratnidal ventilator the cylindrical shell W, having vertical slots in its cylindrical portion and an open center, may be placed about the flange of the grate E, and still another cylindrical shell,V, having vertical slots, may be inserted in the central aperture in the cylindrical shell W and supported thereby, and if desired to use one of said cylindrical shells and to close the central opening therein a plate X may be placed over said central aperture. If desired to use still another attachment in place of the cover X, a grate U, having radiating bars, may be positioned inside of the shell W, with the shank portion U of said grate U resting in the central aperture of the grate E.

In order to allow air to enter the compartment intermediate the ring D and the flange K, I provide ducts D which are shown in the rear portion of the body of the stove, while similar ducts D lead to the space intermediate the flanges K and K Referring to Fig. 14 of the drawings, I have shown athimble N of truncated conical shape which. is adapted. to fit over and rest upon the flanges of the fire-pot N, and said thimble is provided with a series of radial longitudinally-disposed flanges N intermediate which are elongated slots N, through which the heated air radiating from the conical-shaped member N is allowed to pass into the hot-air chamber before entering the conveying-chamber S. Said thimble extends nearly the length of the cone N and serves the purpose of preventing the stove from making a small rootn too hot, because the thimble will interpose a wall between the cone and the drum and in some degree arrest the heat, while, in the second place, it will serve as a heating-board, as it will become very hot and radiate its heat into both the column of air that is passing up between the thimble and the cone and also that passing between the thimble and the outer wall of the stove, thus serving for heat what a sounding-board would for sound. If

desired, this thimble may be removed and the stove utilized without it by simply lifting the same off the hole upon which it rests.

As a means for getting the air between the walls of the stove to be heated for use in warming the rooms I have provided a large circular opening in the rear of R near the bottom of the cone, into which a pipe reaching the outdoor space is to be inserted for conveying fresh air into the space between the walls of the stove, there to be heated for warming and ventilating purposes, also other openings in R at base of cone to admit air for same purpose from the room in which the stove is situated, and in the event no fresh-air pipe is necessary or practicable for the circular opening it is to have a grate placed upon it and is also to admit air, as the others, from the same room.

When the fresh-air pipe is inserted in the circular opening, a damper is to be placed in the pipe to control the influx of cold air from outdoors, as the state of the weather or other circumstances mayde-mand. The air admitted between the walls by either or all of these openings is heated all the way up the sides of the cone and passing into the large conveying-pipe S continues to be heated by the smoke-pipe all the way up to its top or to the branch pipes, wherever they may be inserted, when any are used. I have also provided a shield Q attached to the inner side of the upper front door, and when so attached it constitutes a box open only at the upper end. Through the center of the door is a duct similar to D for air to enter into the shield-box, where it becomes hot and passes up out of the box and inward and upward through the apex of the cone, giving further supply of hot air for smoke and gas consuming purposes.

In operation air is allowed to enter the vent- ICO IIC

flues into the chamber between the ringD and the flange K, and coming in contact with the outer circumference of the fire-pot it becomes somewhat heated before passing through the apertures D. After passing through said apertures the air will enter the recesses at the upper end of the shellC underneath the grate. The second current of air utilized for consuming the smoke and gases will enter through the vent-ducts D which communicate with the compartment above the flange K and enter the apertures P into the interior of the fire-box, where the air which has been heated by its circulation comes in contactwith the heated gases in the fire-box and assists in the further combustion of the soot and smoke in the stove.

By the provision of the various adjusting features it will be readily seen that my stove may be adapted for use in burning either coke, wood, anthracite or lump coal, and

slack, and by the provision of the double hot blast the soot and smoke will be thoroughly consumed, thereby securing the maximum heat from the fuel. As the products of coinbustion are so thoroughly consumed, very little smoke, gases, and soot are encou ntered.

\Vhile I have shown a particular form of apparatus embodying the features of my invention, it will be understood that I may make alterations in the detailed construction of the same, if desired, without departing from the spirit of the invention.
